More on drugs

When plants are attacked by pathogens they produce chemicals to protect themselves which contain antibacterial effects that protect the plant against bacteria.

Antiseptics

Antiseptics are chemicals that destroy bacteria or stop them from growing.

Antiseptics are used outside the body to help clean wounds and surfaces. They are used to prevent infection rather than treat it.

Antibiotics

Antibiotics are drugs used inside the body usually taken in the form of a pill or injection.

They are used to treat patients who are already infected with bacteria or fungi. However antibiotics don't destroy viruses.

There are two types of antibiotics:

Antifungal antibiotics are used to treat fungal infections. They work by killing the fungi or stopping them from growing.

Antibacterial antibiotics are used to treat bacterial infections. They work by killing bacteria or stopping them from growing,

However bacteria can mutate and evolve and sometimes become resistant to an antibiotic. This means when you treat the infection only the non-resistant bacteria will be killed whereas the individual resistant bacteria will survive and reproduce.

The population of the resistant strain will increase which could cause a serious infection not harmed by an antibiotic.

Misuse of antibiotics (e.g. doctors over prescribing them or patients not finishing the course of their antibiotics) has increased the rate of development of resistant strains.
